RAIL-JOINT..

No. 807,1 1e.

Speccation Of Letters Patent.

Patented Dec. 12, 1905.

Application filed September 6, 1905. Serial No. 277,197.

To @ZZ whom, it may concern: A

Be it known that I, JAMEs S. IMEs, a citi- Zen of the United States of America, residing at McKeespOrt, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail- Joints, Of'which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rail-joints.

The invention particularly embodies a railjoint in which the fish-plates are formed with shoulders upon the upper ends thereof and with enlarged base portions, said fish-plates peing united together by integral clampingars.

The advantage accruing from the construction above set forth is that any pressure exerted uponthe tread of the rail by a passing train will serve tO tighten the joint instead Of loosening the same by vibration, as is the case in joints where nuts and bolts Or extraneous fastening means are employed.

The detail construction will appear in the course of the following description, in which reference is had to the accompanying drawings, forming a part Of this specification, like numerals Of reference designating corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved joint. Fig. 2 is a transverse section thereof. Fig. 8 is a side elevation Of my improved fishplate. Fig. 4 is an end view thereof. Fig. 5 is a front elevation of the clamping-bar uniting the fish-plates. Fig. 6 is a perspective view of the joint mounted upon a tie.

My improved rail joint comprises fishplates 1, arranged On each side Of the rail 2, the plates 1 being counterparts in construction. Each plate 1 is formed at its upper edge with a shoulder 3, adapted tO bear against the underneath surface 4 Of the tread of the rail.

The fish-plate 1 is formed with a longitudinal V-shaped recess 5 for the reception of the flange of the rail and beneath said recess with an enlarged fianged portion 6, the upper surface of which forms one side of the recess 5 and the edge of which is in the same plane as the inner surface of the fish-plate 1.

The fish-plates 1 are disposed On each side of the rails 2, adjacent and uniting the meeting ends thereof. The plates are held in position by virtue of yoke members 7, which are formedwith a fiat surface or seat 8 bearing against the underneath surface Of the flange portions 6 of the fish-plates and which are formed with inclined upwardly-projecting arms 9, adapted to engage the inclined sides 10 of the enlarged base of the fish-plates 1. The upwardly-projecting arms 9 gradually decrease in thickness tO their edges and extend over the inclined sides 10 Of the enlarged bases of the fish-plates to a point approximately vertically over the edges of the base Of the rail. The enlarged bases of thefishplates incline upwardly from their outer edges and extend to a point approximately midway Of the height of the web of the rail and then extend upwardly On a vertical line to the edge of the shoulders 3, and the web of the rail is therefore embraced by the heavy and rigid portions Of the fish-plate on each side, while the head of the rail rests firmly upon the shoulders 3 3. The lower surfaces of the arms 9 conform to the angle Of. the inclined portions Of the bases of the fish-plates, and the rails are therefore seated in a practically solid unyielding body Of metal composed Of the fish-plates 1 1, while the latter are rigidly held in engagement with the rail by the yoke members 7.

What I claim, and desire to secure by Letters Patent, is-

A rail joint comprising, in combination with railsections, iishplates arranged on each side thereof, each fish plate being formed with a recess adapted tO receive one side of the base Of the rail and each fish-plate having a base portion inclining upwardly on its upper side from the Outer edge of the fishplate to a point substantially midway of the height Of the web of the rail and a vertical portion extending above the base portion and terminating at its upper edge in a shoulder bearing against the lower surface of the head of the rail and yokes embracing said fish-plates, each yoke being composed Of a single piece having two upwardly and inwardly projecting arms, which decrease in thickness gradually to their inner edges and extend Over the inclined upper surface of the base portions of said fish-plates.

In testimony whereof I affix my signature in the presence Of two witnesses.

JAMES S. IMES.
